[Dovecot] dovecot 2.0rc2 Cannot delete a folder with Thunderbird (delete, not move to Trash)

[Sven Kirmess]

With Thunderbird 3.1 I can now "delete" a folder which moves it to
Trash. But I cannot remove the folder in Trash.

The following is from the Thunderbird log file:

248[6814c00]: 8103800:imap.kzone.ch:A:SendData: 64 rename "test10"
"Trash/test10"

248[6814c00]: 8103800:imap.kzone.ch:A:CreateNewLineFromSocket: 64 OK
Rename completed.


248[6814c00]: 8103800:imap.kzone.ch:S-Trash/test10:SendData: 70 delete
"Trash/test10/"

248[6814c00]: 8103800:imap.kzone.ch:S-Trash/test10:CreateNewLineFromSocket:
70 NO Invalid mailbox name: Trash/test10/


I can confirm that dovecot cannot delete a folder if the name is ended
with a slash.

b list "Trash/x" *
* LIST (\HasNoChildren) "/" "Trash/xx"
* LIST (\HasNoChildren) "/" "Trash/x"
b OK List completed.
c delete "Trash/x"
c OK Delete completed.
d delete "Trash/xx/"
d NO Invalid mailbox name: Trash/xx/

Let me know if that's a Thunderbird bug and I'll open a ticket with
Thunderbird. (But I hope it's a dovecot bug as dovecot bugs actually
get fixed, fast. :-)
